Optoelectronic Instrumentation

Recommended Prerequisites

Electronics, Waves and Optics.

Teaching Methods

The syllabus themes are presented using examples and applications in the field of biomedical engineering. Laboratory classes. Solving (in group and with supervision) engineering problems requiring the joint application of concepts from different syllabus chapters and intensive use of equipment and components data sheets. Mandatory presence in seminars addressing syllabus themes. Small instrumentation project with public oral presentation. Presentation and discussuion of scientific papers in the field. Final exam without consultation.

Learning Outcomes

The goal of this curricular unit is to transmit to the students the following knowledge and skills:

-physical principles and technical features of lasers and light detectors available in the market

-optical properties of most biological tissues.

-interaction mechanisms between light and biological tissues.

-fundamentals of fiber optics and optical communications.

-the fundamentals of advanced imaging techniques: optical coherence tomography, fluorescence microscopy (single and multiphoton).

-to understand the data sheets produced by manufacturers of lasers and light detectors.

-to evaluate the irradiance of an image and calculate the signal-to-noise ratio of a detected image or optical signal.

-to calculate the maximum permissible exposure (ocular) and the nominal ocular hazard distance for laser radiation, in accordance with the IEC/EN 60825.1 Standard.

-to specify protection goggles against laser radiation in accordance with the IEC/EN 60825.1 Standard.
